A workflow is configured so the transition has the User Is In Any User check set to 'jsu-technical-user' user only. This is a user account that does not belong to an actual person but is used for all kinds of automations. It has more permissions than normal users, so automations can do things that would be restricted for normal users. A normal user viewing an issue in that workflow will not see the 'Automation' automation transition.
This is a perfect use case to hide a transition that will be triggered by a 'perform as user' (impersonate) post function. Here you would also configure 'jsu-technical-user' as the 'perform as user' in the post function.

You might restrict some transitions in your workflow to a manager or deputy. For such cases, you might also consider other conditions like 'User Is In Any Groups Groups’ condition or 'User Is In Any Roles' condition.
